You can use the fractions 3/18 and 5/12.
Hope this helps :)
1a. x = 70
Alternate Interior Angles
1b. x = 120
Alternate Interior Angles
1c. x = 110
Corresponding Angles
2a. x = 100
Alternate Interior Angles
y = 80
Supplementary Angles (with x)
2b. x = 75
Corresponding Angles
y = 105
Supplementary Angles (with x)
2c. x = 70
Same-Side Interior Angles
y = 110
Supplementary Angles (with x)
Try the rest on your own!
I believe that the answer would be:
g(x) = 12x + 17
